.7b oZE whom t may concern Be it known that l', CHARLES H. SPEGK- tiran, a citizen of the United States, residing in Philadelphia, Pennsylvania, have inventd certain Improvements in Radiator Cony nections, of which the following is a Specification. Y

My invention relatesto valve connections for radiators of hot water heating systems and particularly to that type oi valve connection which serves to separate the inlowing volume of hot water from the outflowing volume of cooler water, the object of ynay invention being to provide a valve coni nection of this type which will permit of a cmnpact disposal ot the devices connecting the saine with the .main or mains, and Willprovide for the cutting out of the radiator' troni the circulating system While still per` niitting a slow circulation of the water through the connections between the radiator and the supply pipe or main.

ln they accompanying drawing Figure 'l is a longitudinal vertical sectional view of part ot a radiator with valve connection in accordance with my invention, the valve being :.uljustcd to position for directing the waterio the radiator and discharging the cooler water therefrom; F ig. 2 is a similar view showing thc valve adjusted to po sition ior cutting out the radiator from the system butI permitting a slow flow of the water through the valve connection, and Fig. 3 is a longitudinal sectional view illustrata special feature of construction of 'one of the parts of the connection. l

ln the drawing, l represents the rst section-ot a radiator. `Screwed into or otherwise secured to the lower portion olsaid radiator section is the casing?. of the valve connection, which consists of a Vhorizontal tube with two vertical branches 3 anda, and an internal horizontal partition 5, the 1atter being located, by preference, closer to the bottom than to the top of the casing 2 and being upturned at its inner end, as illustratedat 6, while its forward end termi- .Hates iiush with the bore of the outer vertical branch l. To this bore is tted the valve 7 which consists of a hollowA cylinder closed at the top and open at the bottom but having at one side a port v9, and at the opposite sidea port 10, the top of the cylinder having a vertical stem l1 which passes through a suitable stutlng box -on the top of the casing 2 and is provided with a handle whereby it may be conveniently turned.

The branches 3 and 4 of the rvalve connection are in line longitudinallywith one another and with the longitudirial'line or the radiator, so that said branches can be vreadily connected, b v short pipes and el?.

`bows,with branches on the incoming and return mams, or with branches disposed one alongside of the other and'projccting from the inner side of a single supply pipe or main such as is employed in one-pipe heat ing systems. The'radiator can therefore be located close to the main or mains and the simplestform 'of pipe connections can be used between said main or mains and the valveconn'ection of the radiator.

The branch 4 oi the valve connection is the inlet or supplyV branch and in a one-pipe system its pipe connections communicate with the upper portion of the main for renl ceiving the hot water therefrom, the branch 3 constituting the outlet or discharge con Anection and its pipe connections communicating with the lower portion of the :1min in Which the cooler Water circulates. When the valve 7 is adjusted to the position shown in Fig. l the passage below the partition 5 is cut olf from communication with the branch 4, but the/hot water can pass freely through the port 9 of the valve into the pa sage above the partition from which it is discharged into the 'first section of the radiator, the upturned inner end of the par tition 5 tending to direct the supply of hot water upwardly into said radiator section. The Water, cooled by its circulation through the sections of the radiator, accumulates in .the lower portion of the same and passes out beneath the partition 5 to the discharge branch 3. By reversing the position of the valve 7, as indicated in Fig. 2, the passage above the vpartition 5 yis'cut oit from com-- municationywith the branch 4 and the inflow of hot water to the radiator is thereby ar rested, but the port 10 serves to open communication between the branch 4 and the passage below the partition 5, and thus permits floiv of water in limited volume from the branch 4l to the branch 3, thereby providing for a slow circulation of the water from the main to and through the valve connection without any corresponding flow through the sections of the radiators.

Instead of turning up the inner end ot propria@ onggo provide f0.1. the dis change ottime coo Water from'any desxred mufutng with both the lippe? :md ocsox om1'nbers ah! n4 hollow plug vulve, fiiim. to said out-e3? veyicol bunch und lmvng o1:F posi'ily gposed ports offholohy, Whom the valve. is adjusted in @no position, smid brunch will 'no in 'communication with the oppor chamber but 'will 'no ont o from tho www ohariibel and, when the mvo in the, opposite position, said branch wiH bo out oi from the upper chamber :md in. conmmnication with the lower chamber.
